IMB-RMA Benchmarks#
Intel(R) MPI Benchmarks provides a set of remote memory access (RMA) benchmarks that use the passive target communication mode to measure one-sided operations compliant with the MPI-3 standard.
IMB-RMA Benchmark Modes#
When running the IMB-RMA
benchmarks, you can choose between the
following modes:
Standard (default) or multiple mode. You can enable the multiple mode for all IMB-RMA benchmarks using the
–multi <outflag>
command-line parameter. For details, see Running Benchmarks in Multiple Mode.Aggregate or non-aggregate mode. For details on these modes, see the MPI-2 Benchmark Modes chapter. Some
IMB-RMA
benchmarks support the non-aggregate mode only. To determine which benchmarks can run in the aggregate mode, see Classification of IMB-RMA Benchmarks.
